Round 2 of the 2019 Canadian Championship started at 10am, Friday April 19.
All games from the Zonal are replayable in the game viewer below.
One noteworthy round 2 pairing was between the #1 and #3 CFC-rated Canadian women: WFM Svitlana Demchenko vs WGM Qiyu Zhou. The two were Olympiad teammates in 2018, and members of the RA Chess Club until university intervened this past September. Svitlana's play has become noticably more attack-oriented since studying Judit Polgar's books; and here she commits to an objectively dubious attack... but one that requires cool and accurate defence...
